PRUNING IMPLEMENT.

Specification of Letters Patent.

Patented Nov. 7, 1905.

Application filed February 24:, 1905. Serial No. 247,096.

To all whom it may concern.-

Beit known that l, GEORGE E. WRIGHT, a citizen of the United States ofAmerica, residing'at Leetsdale, in the county of Allegheny and State ofPennsylvania; have invented certainnew and useful Improvements inPruning Implements, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in pruningimplements;-

and the invention has for its object to provide a novel form of pruningimplement which is particularly adapted for pruning or shearing thelimbs of a tree.

Thepruning implementis constructed upon the principle of toggle-levers,the opposing blades of the implement being carried bypivotally-connected toggle-levers.

The pruning implement is particularly adapted for overhead work whichcannot be conveniently reached by a person "standing upon the groundorfrom the tree to be pruned;

and I have constructed one of the blades of the implement whereby it canbe hooked over the limb or twigto be pruned to partially support thepruning-knife and facilitate the person using the same in operating theknife to cut the limb or twig. 30

pruning implement, partly broken away.

Fig. 2 is an edge view of the same, and Fig. 3 is a detail perspectiveview of a modified form of knife-blade which can be conveniently usedinconnection with my. improved pruning-knife. A

7 To put-my invention into practicefI employ'a kniferblade 1 of asubstantial hook shape, saidblade having a circular cutting edge, asindicated at 2. The shank portion 3 of the blade is provided withabracket 4, and

between said bracket and the shank of the blade is pivotally mounted alever 5 by abolt and nut6. The one end of the lever 5 is enlarged,asindicated at 7, and pivotally attached to. said end by a nut and bolt8 is a circular wheel 9 having a cutting edge 10, and this wheel formsthe opposing blade to the hookshaped blade 1.

The reference-numeral 11 designates a lever which is provided withbrackets 12 and 14:, and between the end of the lever 11 and the bracket12 is pivotally connected by a nut and bolt 15 the end of the lever 5.The opposite end of the lever 11 is annular in form, as indicated by thereference-numeral 16, and is preferably screw-threaded, whereby it canbe secured in the end of a suitable handle 17 Contiguous to the annularportion 16 of the lever 11 I provide the bracket 14, and the end of alever 19 is pivotally mounted between this bracket 14: and the lever 11by a nut and bolt 20. The opposite end of the lever 19 is pivotallymounted by a nut and bolt 21 between a bracket 22, carried by the shankportion 3 and the lower end of said shank portion. 7 In Fig. 1 of thedrawingsI have illustrated by dotted lines the position my improvedpruning implement assumes when severing a limb or twigfrom a tree, andwhen used for this purpose it is only necessary to engage the hookedblade 1 over the limb or twig and pull downwardly upon the handle 17 ofthe pruning-knife, this movement causing the revoluble cutter-wheel 9 tomove into close proximity to the hook-shaped blade 1.

In Fig. 3 of the drawings I have illustrated a knife-blade 23, which maybe used in lieuof the rotary cutterwheel 9, as this form of knife isparticularly adapted for small limbs and twigs. Inconnection with myimproved knife I may use a handle comprising a plu rality of telescopicsections, which can be conveniently used where difierent heights are tobe reached by my improved knife.-

It will be observed from the foregoing description, taken in connectionwith the drawings, that my improved pruning implement is extremelysimple in construction, strong and durable, and comparativelyinexpensive to manufacture, and while I have herein illustrated thepreferred manner of constructing the same I do not care to confinemyself to the particular arrangement of the toggle-levers nor thecontour of the hook-shaped blade, as thisblade may be readily formed ofa substantial size and contour to engage large limbs of a tree.

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit and scope of theinvention.

I a lever 11 pivoted to the ends of the first-mentioned levers, andhaving an extension forming an operating-handle, substantially asdescribed.

In testimony whereof I afiiX my signature in the presence of twoWitnesses.

GEORGE E. WRIGHT.
